Bring the milk to a boil and chill. Mix the ingredients for the marinade.
Pierce the skin of the melanzane several times with a kitchen knife and cook the melanzane until they are soft (in the stove at 250 °C , takes about half an hour). When they are cool enough to touch, remove the skin and marinate the melanzane for twenty minutes until the flesh turns white.
Drain well, place in a large enough bowl and mash with a wooden pestle or spoon.
Melt the butter in a saucepan, add the flour and stir to make a roux in two minutes. Remove from heat and fold in the eggplant puree with a wooden spoon. Add the milk, let it boil, season with salt, put on fire again and make two min stirring continuously until the mixture has the consistency of yogurt. Add the cheese, stir until it is absorbed, then remove from heat.
Served hot.
(*) Kasar cheese: firm white cheese made from sheep’s milk. It can be replaced by another sheep’s milk cheese – if necessary by a mild Gouda or possibly Cheddar.
Tip: The higher the fat content in the yogurt, the more aromatic and creamy the result!
